ABSTRACT:
The graphics display system comprises a plurality of heads. Each of the heads includes a VGA controller and each of the heads is adapted for a display. The display system also includes a host coupled to the heads, wherein all the standard VGA settings for each of the heads could be programmed by a single command by the host. A method and system in accordance with the invention includes one VGA controller per head. In a broadcast mode a write transaction from the bus is broadcast to both heads. The output timing registers specific to a non-CRT output are not broadcast. To provide broadcast VGA to a CRT and/or a flat panel, software sets up the timing in extended registers and enables the display devices. The VGA application can provide mode settings via the appropriate write VGA registers and the correct display will be on each head.
